vat polymerization technologies (vat)\nuse the information below to answer the question.\nvat polymerization was first used in the 1980s and is the oldest type of 3d printing\ntechnology that is used today. currently, the two most commonly used methods\nare stereolithography (sla) and direct laser processing (dlp)\nmaterial used\nthe material used in this process comes in a liquid resin form. the printers vat is filled\nwith the liquid polymer and then a laser or an ultraviolet light source is used to cure\nthe material, creating each layer. this process uses a thermoset polymer, which means\nonce it has been cured, it hardens and can not be melted down and repurposed.\ndimensional accuracy\none of the advantages of vat polymerization is the dimensional accuracy of the\nprinted parts. in this process, the material is cured, rather than melted.\nprinting process\nin a \bottom - up\ printer, the vat that contains the resin has a clear base. the build\nplate is lowered from the top of the vat until it touches the bottom. the plate will\nthen raise slightly so that it is no longer in contact with the bottom of the vat. this\nallows the resin to flow in, filling the space in between.\nonce the build plate is in position, the light source will shine through the window onto\nthe plate. the resin that is hit by the light will cure and harden onto the build plate,\ncreating the first layer of the build. the plate will then raise slightly, allowing more\nresin to flow into the gap. afterward, it will lower back down and position itself at the\nright location for the next layer. this cycle repeats until the entire form has been built.\nwhat are the two most common vat polymerization\nmethods?\nstereolithography (sla) and direct laser processing (dlp)\nfused filament fabrication (fff) and powder bed fusion (pbf)\nthermoplastic binding (tb) and polymer distribution (pd)\nmaterial jetting (mj) and binder jetting (bj)
